In this study, effects of P. indica on rice resistance against rice leaffolder (Cnaphalocrocis medinalis Guen?e) were investigated. Growth inhibition and leaf injury caused by leaffolder larvae infestation in P. indica-colonized rice was significantly alleviated. Moreover, growth retardation was observed in larvae which fed on P. indica-colonized plants. JA-Ile levels and trypsin inhibitor activities in leaf tissues of P. indica-colonized plants were higher than those in noncolonized plants under leaffolder-infested conditions. P. indica effects on increasing trypsin inhibitor expression and reducing larval growth were repressed by aspirin. JA signaling drives P. indica-enhanced insect resistance in rice, and trypsin inhibitors might be candidates involved in this mechanism. Changes in antioxidant enzyme activities and malondialdehyde levels in P. indica-inoculated plants were observed, and it was demonstrated that oxidative stress induced by insect infestation could be reduced in P. indica-colonized plants. ? 2021 The Author(s).
